GPU on GRID

See the required underlying steps to enable GPU job submission.

Use Case 1: Direct job submission to a CREAM service

• Acomplished through gpu resource under JDL's CERequirements.

• There is no GPU matchmaking: the grid user needs to know the endpoint to submit to. A basic JDL example could be:

  •     # cat test_cream.jdl
        [ 
            JobType = "Normal"; 
            Executable = "foo.sh"; 
            StdOutput="out.out"; 
            StdError="err.err"; 
            InputSandbox={"foo.sh"}; 
            OutputSandbox={"out.out", "err.err" }; 
            OutputSandboxBaseDestUri="gsiftp://localhost";
    
            CERequirements="gpu==2";
        ]

  Submit the job directly to the CREAM service with glite-job-ce-submit.

Use Case 2: Job submission through WMS
